If the Galaxy S5 does arrive in metal, Samsung will finally be able to compete in the style stakes with the likes of Apple and HTC, whose hewn-from-solid iPhone 5 and One flagships have provided our hands with many joyful hours.

It will be interesting to see whether or not an all-metal Galaxy S5 will retain the popular non-removable battery and microSD slots, attributes which aren't present in the iPhone 5 or HTC One.

While the Galaxy S4 Active has a metal band, its back cover is flexible polycarbonate. A removable metal back cover could be an option for the S5, but its likely that a single piece of carved aluminium will provide a sleeker, more premium finish.

These are, of course, just rumours for the time being – we'll keep our ears to the ground for any more info.
